While the subtitle mentions Heinlein, Hubbard, and Asimov along with John W. Campbell, this is primarily a biography of Campbell centering on his activities as editor of Astounding Science Fiction (later Analog), the largest-circulation and most influential science fiction magazine in the 1940s through the 1960s; the book has a special focus on Campbell’s relationships with the authors he published, his influence on their work, and on the authors’ relationships with each other.

The level of detail in this exceedingly well documented 500-plus-page book is, well, astounding, and the amount of work Nevala-Lee did to produce it must have been equally astounding. The dust jacket copy notes that the author drew on “unexplored archives, thousands of unpublished letters, and dozens of interviews.” It shows.

This is not, however, a dry academic history. Nevala-Lee does a fine job of bringing to life the decidedly oddball quartet listed in the subtitle, along with their wives and girlfriends (some of whom did much uncredited work) and many other sci-fi authors of the time. Nevala-Lee has not, however, produced a hagiography: the portraits of all of these figures are nuanced, bringing out both their attractive and unattractive traits. The attractive traits include. in all but Hubbard, dedication to work and writing, the authors’ and Campbell’s mutual support, and in Campbell’s case a messianic belief in the transformative power of science fiction. The unattractive traits include spousal abuse and pathological lying (Hubbard), right-wing authoritarian politics (Hubbard, Campbell, and Heinlein) and denunciations of associates to the FBI as “communists” (Hubbard). (For a good dissection of Heinlein’s most authoritarian work, see Michael Moorcock’s famous takedown of Starship Troopers, “Starship Stormtroopers.”) Even Asimov, who comes off as by far the most sympathetic of the quartet, had a serious flaw: engaging in serial sexual harassment.

For those interested in cults, there’s also a great deal of material on Hubbard’s and Campbell’s formulation of dianetics — basically a rehashing of Alfred Korzybski’s tedious and trivial “general semantics” concepts along with (though they wouldn’t have known the term) abreaction therapy (which can be quite dangerous), all with a “cybernetics” overlay — and their subsequent falling out prior to Hubbard’s coming up with the term Scientology, founding of that “church,” and installation of himself as that money-making machine’s glorious leader.

This brief summation only scratches the surface, and anyone interested in science fiction and its history should have a great time delving into this well researched, well written book.
